Learning the id tech 3 engine

I accidentally deleted this from Dev.to.

It was an incredible honor and privilage to read and study the Quake 3 source code. I attempted to fix an outdated port of ioquake3 to emscripten called quakejs. Someone else in the thread was able to get the new version of emscripten working. I challenged myself to learn more C code and the engine by updating the emscripten hooks to the latest version of ioq3.

I created tons of branches while dissecting the code. Normally this would likely be done using tags, but I like seeing the tree of changes.

I had to understand every line of the quakejs changes, and then systematically go back in the version history and learn why the code had changed. A lot of code was moved in a large renaming commit, so it was easy to port the changes. A big part of my confusions was learning how compiler templates work in C.

There are a lot of beautiful open source mods available for quake 3, it would be interesting to me to see what kind of changes these mods have implemented.

It would be amazing to reintegrate the level editor in to the game engine like Time Splitters.
